INVENTOR: NELS H. NYQUIST BY ATT'YSY 3,038,196 DGUR HINGE Nels Herbert Nyquist, 1257 Early Ave Chicago, ill. Filed Get. 26, 1%9, Ser. No. 848,731 9 Claims. (Cl. 16-164) This invention relates to improvements in hinges of a type especially adapted for use with the doors of wall cabinets.

The main objects of this invention are to provide an an improved form of hinge for doors swinging into and out of a position in coplanar relationship with the wall which forms the opening closed by the door; to provide an improved hinge of this kind especially adapted for use with wall cabinets when set into wall openings with the front of the cabinet door flush with the wall; and to provide an improved form of hinge of this kind which is simple in construction, hence economical to manufacture, and offering rigid support for the door in any position to which it may be shifted between fully closed and open positions.

In the adaptations shown in the accompanying drawings:

FIG. 2 is an enlarged, horizontal, cross-sectional view, taken on the plane of the line 2-2 of FIG. 1, of an improved form of hinge constructed in accordance with this invention;

FIG. 3 is a similar view showing the hinge in its full open position, exterior parts being broken away to more clearly illustrate the internal parts;

FIG. 4 is a partly sectional view of the hinge taken on the plane of the line 4-4 of FIG. 3;

FIG. 5 is a view similar to FIG. 3 showing, in open position, a modified form of hinge constructed in accordance with this invention;

FIG. 6 is a plan view of the same form of binge in closed position; and

FIG. 7 is a partly sectional, elevational view taken on the plane of the line '77 of FIG. 5.

The essential concept of this invention involves a bracket and a plate interconnected by a shifting pivoted member and a pair of links so as to permit swinging of the plate between a position of longitudinal parallelism with the bracket and a position of right angular relationship to the bracket whereby, with the bracket secured in the wall opening and the plate mounting a door dimensioned to form a closure for the opening, the door is swingable into and out of a position flush with the wall.

A hinge embodying the foregoing concept comprises a bracket 8 (8) and a plate 9 so interconnected by a member 10 (10') and a pair of links 11 and 12 (12') that, with the bracket 8 (8') secured to a wall 13 defining an opening 14, a door 16, secured to the plate 9, may be swung into and out of a position flush with the wall 13.

The bracket 8, as here shown, is formed of a pair of rectangular-shaped panels 17 and 18 secured in parallel position by spacers 19 extending around three perimeters of the panels. This provides an opening 21 along one lateral side through which the member 10 and the links 11 and 12 enter and recede during the swinging of the door 16 between its closed and open positions. One outer corner of the bracket 8 is cut away at (20') (FIGS. 3 and 5) to insure seating of the adjacent end of the plate 9 and its pivotal connection to the member 10 (10'), as clearly shown in FIGS 2 and 6.

The bracket 8 (8') is intended for positioning on the wall 13 along the top and bottom areas which define the 3,@33,l% Fatented June 12, 1962 opening 14, as shown in dotted outlines at the upper and lower left corners of FIG. 1. As shown in FIGS. 2, 3, 5 and 7, the bracket 8 (8') is set with one end up against the vertical area of the wall 13, inwardly from the front face of the wall 13 a distance but slightly greater than the combined thickness of the door 16 and its supporting plate 9.

The plate 9 is a. fiat strip with a pair of ears 22 struck out from the face thereof as closely adjacent as possible to one end. Another car 23 is struck out from the same face of the plate 9 the requisite distance inwardly from the ears 22, as determined by the character of the links 11 and 12. The plate 9 is formed with suitable holes for the insertion of fasteners to secure the door 16 to the plate 9.

The member Ill, as here shown, comprises a pair of irregular-shaped parts 25 suitably secured together in spaced parallel relationship to form an opening to receive the link 12 when the door 16 is in its fully-closed position. At its outermost corner, the member 14} is connected by a pivot pin 24. to the pair of ears 22 on the plate 9. Adjacent its almost diagonally-opposite end, the member 19 is formed with a transverse, elongated slot 26 in which fits a noncircular post 27 secured to the bracket 8 (panels 1718) by a pivot pin 28, thus providing a sliding pivotal connection of the member 10 to the bracket 8.

The links 11 and 12 are secured together at their opposed ends by a pivot pin 29 and at their opposite ends by a pivot pin 30 to the plate car 23 and by pivot pins 31 and 32 to the bracket 8 and member 10 respectively.

As here shown, the link 11 preferably is channelshaped with the opposite ends offset outwardly from the open longitudinal edge, thus giving the link something of an arcuate form. This is to permit a partial nesting of the link 12 (12,) within the link 11 when the member 10 (10) is receded into the bracket 8 (8') upon the closing of the door 16. (FIGS. 2 and 6.)

The link 12 has an enlargement 33 to provide support for the pivot pins 31 and 32 to the bracket 8 and the member 10 respectively. The pivot pin 31, obviously, is fixed to the bracket 8 (panels 17-18) and, as will be noted from the drawings, is located intermediate the pivot pins 28 and 34 The pivot pin 32, is located intermediate the pivot pins 28 and 31 and moves in an are around the pivot pin 31.

In the adaptation shown in FIGS. 2-4 the arcuate slot 34 is formed merely to allow swinging of the member 10 on its pivot 32 which, of course, must extend through both parts 25 of the member 10.

In the adaptation shown in FIGS. 57 the parts 25' of the member 10, have circular openings 35 formed therein inwardly adjacent from the end of the member 10' wherein is formed the slot 26 embracing the guide member 27' on the pivot pin 28' secured to the bracket plates 17 and about which pivot pin 28' the member 10' swings in the opening and closing of the door 16. The link 12 here is shown as two superimposed pieces (FIG. 7) with the enlarged opposite end presenting oppositelydisposed disks 36 dimensioned to seat in the respective openings 35 in the parts 25 of the member 10' concentrically of the pin 32'. This link 12, however, is pivotally connected to the member Ill by the disks 36. A pin 31 extends through these disks 36 and through the plates 17 of the bracket 8' eccentrically of the pin 32' thus pivotally connecting the enlarged end of the link 12' to the bracket 8.

In this adaptation of FIGS. 5-7, the slot 26', in which the guide member 27 reciprocates during the swinging of the door 16, is shorter than the comparable slot 26 in the adaptation of FIGS. 1-5. Moreover, this slot 26 is open at its distal end to permit the guide member 27' to extend beyond the member When the door 16 is swung outwardly from its closed position (FIG. 6) the link 11 is pulled outwardly with the pivotal connection 26' to the link 12 swinging in an are around the pivot pin 31. At the same time the outer end of the member 10', pivoted at 24 to the door plate 9, is swinging outwardly of the bracket 8' and the pivot 32 is swinging rearwardly about the pin 31' from the position shown in FIG. 6 to the position shown in FIG. 5.

A door 16, for almost any kind of an opening and especially for a wall-recessed cabinet, mounted on hinges of the type herein disclosed, when closed, positions the plate 9 in longitudinal parallelism with the open side of the bracket 8 (8) and the door is flush with the wall 13. When the door 16 is in its full open position the plate 9 is disposed in right angular relationship to the open side of the bracket. The door 16, likewise, is disposed substantially at a right angle to the wall 13.

It is to be understood that numerous details may be altered or omitted without departing from the spirit of this invention as defined by the following claims.
